The ASA 5500 Series offers both IPsec and SSL VPN on a single platform, eliminating the
need to provide parallel solutions. In addition to VPN services, the ASA 5500 Series offers
application inspection ?¬?rewall and intrusion prevention services.
Cisco remote-access VPNs are able to use three IPsec clients: the Certicom IPsec client, the
Cisco VPN Software Client, and the Cisco VPN 3002 Hardware Client. Details are as
follows:
?– Certicom client: A wireless client that is loaded onto wireless personal digital
assistants (PDA) running the Palm or Microsoft Windows Mobile operating systems.
Certicom wireless client software allows companies to extend critical enterprise
applications, such as e-mail and customer relationship management (CRM) tools, to
mobile professionals by enabling handheld devices to connect to corporate VPN
gateways for secure wireless access.
